Gas Safe boiler repairs, service and installations, right here in Radlett
Radlett sits a short drive from our Borehamwood base, so a call-out here doesn’t mean a long wait for an engineer to cross town.
We diagnose before we quote. Ignition faults, pressure loss, PCB and fan issues; each has a specific cause, and we test for it rather than swapping parts and hoping.
If the boiler’s had its day, we’ll tell you. Age, repair history, and cost all factor into that call. You’ll get a straight answer, then a fixed installation price if replacement’s the right move.

Our most common Radlett boiler jobs
From breakdowns to brand-new installations, here’s what our engineers handle most.
Fault Finding & Repairs
Ignition faults, dead PCBs, ropey fans; the usual suspects behind a boiler that refuses to start. We test rather than swap parts blind.
New Boiler Installations
Right-sized combi, system, or regular boiler for your property, fitted with the warranty registered and building regs signed off.
Boiler Upgrades & Conversions
Swapping out an ageing back boiler, moving to a combi, or adding an unvented cylinder when an older heating setup needs modernising.
Landlord Gas Safety Certificates (CP12)
Legally compliant gas safety inspections for landlords in Radlett, with certification issued once the check is complete.
No Heat, No Hot Water — Priority Callouts
A cold house goes straight to the front of the schedule, with same-day visits arranged wherever we're able to.
Annual Boiler Servicing
Checked against the manufacturer's own specification — flue, pressure, and combustion — so cover stays valid and problems get spotted while they're still small.

Serving Radlett with Pride
Our base sits just down the road in Borehamwood, close enough that Radlett falls well inside our fastest response times rather than the outer edge of anywhere we cover. When a boiler goes down here, an engineer isn’t crossing half of London to reach you.
We handle the full range of boiler work across Radlett and the WD7 postcode: breakdowns and fault diagnosis, annual servicing, CP12 landlord certificates, cold or unresponsive radiators, powerflushing for sludged-up systems, and routine gas appliance safety checks. If a job turns out to involve more than the boiler itself, our engineers also cover general plumbing, drainage, and water leak detection, so you’re not left chasing a second contractor for a related issue.

Radlett Boiler FAQs
Common questions about boilers, answered plainly. If you don't see what you're looking for, call us on 02081080400 and we'll talk you through it.
How fast can you get an engineer out to Radlett?
Our base is in Borehamwood, a short distance away, so Radlett sits well inside our quickest response window. No-heat and no-hot-water calls go to the top of the list.
Should I repair my boiler or just replace it?
It comes down to age and how often it’s been breaking down, more than anything else. We’ll look at the unit in person and give you a straight steer rather than pushing one option over the other.
Does the warranty get sorted if I have a new boiler fitted?
Yes. Registering the manufacturer warranty and handling the building regs paperwork is part of the installation, not an extra step.
Can a CP12 certificate be issued the same day?
In most cases, yes, provided the visit’s already booked in and the check goes ahead as planned.
What happens if parts aren't available for an older boiler?
We’ll raise that during diagnosis and talk you through whether a repair still makes sense before any work is agreed.
Is £99 the total cost of a repair?
That covers the first hour, with a half-hour rate coming into effect after that. Most repairs are wrapped up within an hour or two, and either way you’ll have a fixed price agreed before we start, not once we’ve finished.
